> This negative test expect HadoopIllegalArgumentException on illegal configuration. It
uses JUnit (expected=HadoopIllegalArgumentException.class)  and passed fine on Linux.
> On windows, this test passes as well. But it left open handles on NN metadata directories
used by MiniDFSCluster. As a result, quite a few of subsequent TestBalancer unit tests can't
start MiniDFSCluster. The open handles prevents them from cleaning up NN metadata directories
on Windows. 
> This JIRA is opened to explicitly catch the Exception and ensure the test cluster is
properly shutdown.
